What is the primary function of the AOA computer in an aircraft?

The primary function of the AOA (Angle of Attack) computer in an aircraft is to measure the angle of attack. This measurement is crucial for several reasons, primarily related to flight safety and performance. The angle of attack is the angle between the wing's chord line and the oncoming air. Monitoring this angle helps pilots understand the aerodynamic state of the aircraft, particularly in relation to stall conditions.

By measuring the angle of attack, the AOA computer can provide critical data that informs pilots about the aircraft’s lift characteristics. If the angle of attack is too high, it can indicate an impending stall, allowing pilots to take corrective action. The information from the AOA computer is also used in advanced flight control systems to enhance safety and performance across various flight regimes.

In contrast, while controlling engine throttle, monitoring fuel efficiency, and managing electrical systems are all important functions in an aircraft, they are outside the primary role of the AOA computer, which is specifically focused on the measurement and analysis of the angle of attack for safe flight operations.
